110 DAIRY FARMING 



brewery. Considerable objection has been raised by city 

 health authorities to the use of this feed. If fed in moderate 

 amounts under proper sanitary conditions, it is not ob- 

 jectionable. However, the use of it is so often abused that 

 officials in some localities have found it easier to prohibit 

 the use than to regulate it. The objection comes from 

 feeding these grains exclusively, from allowing decomposi- 

 tion to begin before feeding, and from the very objection- 

 able sanitary conditions that exist if special care is not taken 

 to keep the feed boxes, feeding troughs, and, in fact, the 

 entire stable, clean. This feed should not be used in excess 

 of twenty pounds per day, and should be supplemented with 

 hay and some other grain, such as corn. 



The greater part of the brewers' grains now produced are 

 dried, and in this form may be transported long distances. 

 This feed is rich in protein. Four or five pounds may be 

 used in the ration to advantage. At present the larger part 

 of this by-product finds a market in Europe. 



106. Mixed Feeds. No small proportion of the grain 

 supplied the dairy cows of the United States is in the form of 

 mixed feeds. As a class, mixed feed is to be looked upon 

 with suspicion. Where the unmixed grains and by-products 

 may be bought on the market, it is always safer to purchase 

 them and to make such mixtures as may be best to supple- 

 ment the available farm feeds. The main purpose of the 

 manufacturers or dealers in putting feed mixtures on the 

 market is to dispose of material of inferior quality or of some 

 by-product of little or no value. One of the most common 

 ingredients of mixed feeds is oat hulls, from oatmeal factories. 

 In many cases the hulls are ground fine to escape detection, 

 and the claim is made that ground oats is a part of the 

 mixture. A careful examination will usually disclose the fact
